Hey

I have my mind set on getting a hooker or flowmaster catback exhaust. They both sound good but I want to know which will give me the most HP.

Thanks

 

From a recent post, there was a link to a some flow charts of both systems, but I forget the link. The Hooker outflowed and created more HP, but that was on a larger engine so the % of HP was greater, you probably wouldn't notice the difference with your setup.
